* gdesktop.c (setup_icon_dnd_dest): Always specify ACTION_MOVE,
	since we want to be able to move the icons around.  Connect to the
	drag_motion signal.
	(dnd_icon_targets): List desktop icons as a target to be able to
	move them just a notch in the desktop.
	(icon_drag_motion): Decide which action we can use for dropping
	stuff on a desktop icon.
	(setup_icon_dnd_dest): Always specify all the actions.
	(icon_drag_data_received): Allow for icons to be moved just a
	notch by accepting drops from icons.

	* gdnd.h: Added #defines for the DnD target type names.

	* gdnd.c (gdnd_init): New public function to intern the target
	atom names.
	(gdnd_drag_context_has_target): New public function to see if a
	drag context has a certain target type.

	* gdesktop.c (setup_desktop_dnd): Do not use
	GTK_DEST_DEFAULT_MOVE, and connect to drag_motion.
	(desktop_drag_motion): If we are dragging from a desktop icon,
	indicate the action as MOVE.  Otherwise, force the action to be
	LINK unless the user explicitly requested ASK.
	(setup_desktop_dnd): Intern the atoms for the drop targets.
